CONFIRMATION OF M-TIP ELECTRO-ABLATION OF PNEUMO-CYSTS FOR TREATMENT OF SPONTANEOUS PNEUMOTHORAX AS A SECONDARY METHOD TO STAPLING

Abstract
Background: We recently established new guidelines for our electro-ablation technique, which has been shown to be a ubiquitous, easy, and cost effective method secondary to stapled resection of pneumo-cysts for the treatment of pneumothorax. The present study was conducted as a confirmation of the effectiveness of this technique.Patients and methods: Between July 1998 and June 2002, 134 consecutive patients with spontaneous pneumothorax underwent surgery. Dependent lesions were resected using staplers. If found, residual lesions were ablated using M-tip electro-ablation (Group M). When the ablated pneumo-cysts were greater than 2 cm in diameter, pleural treatment was carried out by covering the surface with absorbable mesh sheets (Group L).Results: There were 7 cases (5.2%) of relapse of spontaneous pneumothorax and each underwent another operation due to the relapse. None of the lesions in the relapse cases received electro-ablation in the first operation. Relapse-free cases were 77/83 (93%) in Group N (no ablation group), 41/42 (98%) in Group M, and 9/9 (100%) in Group L (p=0.4). Comments: Our results demonstrated the safety and efficacy of our M-tip electro-ablation technique for pneumo-cysts as a secondary method to stapling. We considered that it was useful for the treatment of spontaneous pneumothorax. (198 words)
